What to do if my Panasonic CS-YS9MKV-7 shows Indoor/Outdoor Abnormal Communication?
- MMichael AndersonAug 19, 2025
If your Panasonic Air Conditioner displays an Indoor/Outdoor Abnormal Communication error, it could be due to several reasons: * A faulty indoor or outdoor unit PCB. In this case, you should check and repair or replace the affected PCB. * Signal transmission errors due to incorrect wiring. Inspect the wiring between the indoor and outdoor units to ensure it's correct. * Broken wires in the connection wires between the indoor and outdoor units. Check for any broken wires. * A disturbed power supply waveform. Examine the power supply waveform and correct any disturbances.
